DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Referring to FIGS. 1 to 5 of the accompanying drawings, the reference numeral 1 designates a folding type portable communication device according to the present invention. This device 1 comprises two communication units, namely, a first communication unit 2 and a second communication unit 3. The communication units 2 and 3 are connected to each other in a foldable manner for pivotal movement between a folded position as illustrated in FIG. 4 and an unfolded position as illustrated in FIG. 3. The communication device 1 also comprises a two-level switch 4, a mode selector 5, a vibrator 6, and a sounder 7.

[0026] The first communication unit 2 has a key pad 8 and a microphone 9. In the embodiment, the first communication unit 2 is a rectangular plastic box resulting from assembling a lid 2 a and a housing 2 b by means of fasteners, not shown.

[0027] The second communication unit 3 has a display 10 and a speaker 11. In the embodiment, the second communication unit 3 is a rectangular plastic box resulting from assembling a lid 3 a and a housing 3 b by means of fasteners, not shown. The first and second communication units 2 and 3 are connected to each other by a hinge 12. An antenna 13 is attached to the second communication unit 3 and extends in a direction orthogonal to an axis of the hinge 12.

[0028] The two-level switch 4 has a first level and a second level. In the embodiment, the two-level switch 4 has an ON level and an OFF level, and includes a magnet 4 b mounted within the first communication unit 2 and a detector 4 a mounted within the second communication unit 3 for detecting a magnetic field provided by the magnet 4 b. In another embodiment, the magnet 4 b may be mounted within the second communication unit 3 and the detector 4 a within the first communication unit 2. The two-level switch 4 assumes the first or ON level when the communication units 2 and 3 are folded or closed as illustrated in FIG. 4. It assumes the second or OFF level when the communication units 2 and 3 are unfolded or opened as illustrated in FIG. 3.

[0029] In the embodiment, the two-level switch 4 assumes ON level when the detector 4 a detects the magnetic field Of the magnet 4 b, and OFF level when the detector 4 a fails to detect the magnetic filed of the magnet 4 b.

[0030] In the embodiment, the detector 4 a, which includes a Hall effect element, is embedded within the second communication unit 3 and located in the neighborhood of the speaker 11. The magnet 4 b is embedded within the first communication unit 2 and arranged to come into registry with the detector 4 a when the communication units 2 and 3 are folded.

[0031] The mode selector 5 is operatively coupled with the two-level switch 4 and mounted within the second communication unit 3 that has the detector 4 a. The mode selector 5 provides setting for one of a calling reception vibration mode and a calling reception sound mode in response to the level provided by the two-level switch 4. The mode selector 5 includes a first circuit 14 for driving the vibrator 6 when energized and a second circuit 15 for driving the sounder 7 when energized. The mode selector 5 includes a controller 16, in the form of a large scale integrated (LSI) circuit, for energizing the first circuit 14 upon reception of a calling when the setting for the calling reception vibration mode is provided and the second circuit 15 upon reception of a calling when the setting for the calling reception sound mode is provided.

[0032] With reference to FIG. 2, the first circuit 14 is a vibrator driver circuit. When energized by a control signal from the controller 16, the first circuit 14 drives the vibrator 6. The vibrator 6 is connected to the first circuit 14.

[0033] The second circuit 15 is a sounder driver circuit. When energized by a control signal from the controller 16, the second circuit 15 drivers the sounder 7. The sounder 7 is connected to the second circuit 15 and the speaker 18 to produce sound upon receiving a calling.

[0034] The controller 16 is connected to a memory 17, a main controller, not shown, and the two-level switch A. The memory 17 stores settings for calling reception vibration mode and calling reception sound mode. When a calling reception signal is received from the main controller, the controller 16 energizes the first circuit 14 when the setting for vibration mode is provided, and the second circuit 15 when the setting for sound mode is provided.

[0035] The communication device 1 has a battery case 19 for a battery, not shown.

[0036] With the communication units 2 and 3 unfolded, the controller 16 causes the sounder 7 to produce sound upon receiving a calling. With the communication units 2 and 3 folded, the controller 16 causes the vibrator 6 to produce vibration upon receiving a calling.

[0037] Explaining in more detail, when the communication units 2 and 3 are unfolded as illustrated in FIG. 3, the two-level switch 4 is at OFF level, causing the controller 16 to provide setting for a calling reception sound mode (ON setting) and cancel setting for a calling reception vibration mode (OFF setting). Under this condition, upon receiving a callING, the controller 16 energizes the second circuit 15, causing the sounder 7 to produce sound. When the communication units 2 and 3 are folded as illustrated in FIG. 4, the two-level switch 4 is at ON level, causing the controller 16 to cancel setting for calling reception sound mode (OFF setting) and provide setting for calling reception vibration mode (ON setting). Under this condition, upon receiving a call, the controller 16 energizes the first circuit 14, causing the vibrator 6 to produce vibration. The relationships mentioned above are tabulated as follows: COMMUNICATION VIBRATION DEVICE SWITCH SOUND MODE MODE UNFOLDED OFF ON setting OFF setting FOLDED ON OFF setting ON setting

[0038] From the preceding description, it is now appreciated that, in the embodiment, folding the communication units 2 and 3 provides setting for vibration mode, and unfolding the communication units 2 and 3 provides setting for sound mode. The present invention is not limited to this embodiment. In another embodiment according to the present invention, folding the communication units 2 and 3 may provide setting for sound mode and unfolding the communication units 2 and 3 may provide setting for vibration mode.

[0039] In the embodiment, the two-level switch 4 is at OFF level when the communication units 2 and 3 are unfolded, causing the sounder 7 to produce sound upon receiving a calling. The two-level switch 4 is at ON level when the communication units 2 and 3 folded, causing the vibrator 6 to produce vibration upon receiving a calling. The present invention is not limited to this embodiment. In other embodiment according to the present invention, the two-level switch 4 may be at ON level when the communication units 2 and 3 are unfolded, causing the sounder 7 to produce sound upon receiving a calling, and it may be at OFF level when the communication units 2 and 3 are folded, causing the vibrator 6 to produce vibration upon receiving a calling.

[0040] In the embodiment, the magnet 4 b is brought into registry with the detector 4 a. The present invention is not limited to this arrangement. In other embodiment, the magnet 4 b may be out of registry with the detector 4 a as long as the detector 4 a can detect the magnetic field of the magnet 4 b when the communication units 2 and 3 are folded.

[0041] In the embodiment, the two-level switch 4 employs the magnet 4 b and the detector 4 a. The present invention is not limited to this type of switch. Two-level switches of any types may be used.

[0042] From the preceding description, it will now be appreciated that simple manipulation of unfolding or folding the communication units 2 and 3 can make a switch between sound mode and vibration mode, without any manipulation of key pad.
